Question
The average of Radhika’s marks in 7 subjects is 75.
His average in six subjects excluding science is 72.
How many marks did he get in Science?
Solution
Sure, here is the step by step solution:
Step 1: The average of Radhika's marks in 7 subjects is 75. So, the total marks in 7 subjects = 75 * 7 = 525 marks.
Step 2: The average of Radhika's marks in 6 subjects excluding science is 72. So, the total marks in 6 subjects = 72 * 6 = 432 marks.
Step 3: To find out the marks in Science, subtract the total marks of 6 subjects from the total marks of 7 subjects. So, the marks in Science = 525 - 432 = 93 marks.
So, Radhika got 93 marks in Science.
